Figure 3: Smears produced from lymph node fine-needle samples and examined at low power. Low power assessment shows the differences in cell composition and the presence or absence of cell aggregates in reactive lymphoid hyperplasia (a), marginal zone lymphoma (b), follicular lymphoma (c), mantle cell lymphoma (d), chronic lymphocytic leukemia/small lymphocytic lymphoma (e), and lymphoplasmacytic lymphoma (f). Note the variable size and frequency of aggregates in reactive lymphoid hyperplasia (black arrowheads). Compare with the monomorphism of the small aggregates in follicular lymphoma (white arrowheads) and the absence or vague delineation of aggregates in the other lymphoma cases. Also, there is a markedly more polymorphic cell composition in reactive lymphoid hyperplasia as compared to the other cases. (d: Diff-Quik, all other: May-Grünwald-Giemsa; 10x).
